    Abstract The properties of polyethylene terephthalate (PET) reinforced with 1, 5, 10, 15 and 20% (w/w) alkaline-treated hemp fi bers were investigated following a series of processing stages. The fi ber concentration signifi cantly impacts the compounding process, yielding thermostable composites below 300°C. Their elastic moduli varied logarithmically with fi ber concentration, and were increased by up to 20% with respect to the nonreinforced formulation. Such reinforcement was, however, followed by a drastic decrease in the elongation at break, from more than 20 mm for the unreinforced PET to as low as 2.5 mm. Other properties showed closer observations to the… More >
